Summary: Parthenogenesis, a rare event in birds, has been identified in the critically endangered California condor through parentage analysis. This marks the first molecular marker-based identification of facultative parthenogenesis in an avian species, showing that females in regular contact with fertile males can still reproduce asexually.

Summary: This study compared the gene expression differences between fertilized and parthenogenic turkey embryos at different stages of development. It found that a large number of genes showed differential expression in parthenotes, and several genes, including APOA1, MYBPC2, TCP1, and THRAP3, were up-regulated and may play a crucial role in the development of parthenogenesis in turkeys.

Summary: Over the past two decades, there has been a significant increase in documentation of facultative parthenogenesis (FP) in vertebrates. This reproductive mode has been observed in birds, lizards, snakes, and elasmobranch fishes. The discovery of FP in a crocodilian species, the American crocodile, suggests a common evolutionary origin of FP across reptiles, crocodilians, and birds.

Summary: The free-living amoeba Acanthamoeba castellanii contains two different types of thioredoxin reductases in its genome, with the small TrxR being upregulated in response to oxidative stress. The role of the large TrxR, however, remains unclear in the organism's response to oxidative stress.

Summary: The study proposes an independent baseline search strategy based on satellite density, which ensures that the independent baseline network has sufficient observations and short baselines by calculating the number of co-viewing satellites between stations. Compared to traditional methods, this approach demonstrates the ability to achieve higher positioning accuracy.

Summary: Geographical parthenogenesis is an interesting topic in evolutionary biology, and a novel pattern of geographical parthenogenesis in the isogamous brown alga Scytosiphon lomentaria has been reported in Japan. The study found distinct distribution of sexual and parthenogenetic populations along different ocean currents, and suggested that parthenogens may have evolved at least twice independently in this species.

Summary: This study reports a second case of parthenogenesis in a zebra shark female that was housed with conspecific mature males, questioning the conditions under which elasmobranch females undergo parthenogenesis.

Summary: The study demonstrates that in a population of Brazilian yellow scorpions, there are female individuals reproducing through parthenogenesis. The results from the experiments suggest that asexual reproduction is facultative in this population.

Summary: This study investigates the Marchalina hellenica populations in Greece and Turkey, revealing the presence of male individuals outside of their native range and highlighting a previously unknown role of males in the reproduction of this species. The populations in Greece and Turkey show strong genetic affinity, while human-aided dispersal has potentially affected their genetic pattern.

Summary: The research reveals at least two independent origins of eusociality and solitary behavior in Hymenoptera, as well as two independent origins of thelytokous parthenogenesis from ancestral arrhenotoky. Additionally, accelerated rates of gene duplications, loss, and gain were observed in the lineages leading to D. coccinellae, indicating ancient divergence of Braconid wasps and rapid evolution in response to adaptations to novel hosts.

Summary: The balance between costs and benefits plays a significant role in driving associations between species. In this study, the costs of living in a facultative association between red wood ants and Porcellio scaber were quantified. The results showed that the association incurred several costs for the isopod, including a decrease in density near the ant nest, smaller size of individuals near the nest, a higher proportion of wounded individuals near the nest with higher ant traffic, and a negative impact on reproductive investment in females. However, the red wood ant nests and their surrounding territory provided a stable resource provisioning and protection for the facultative associate.

Summary: In this study, the use of 6-DMAP treatment on canine oocyte activation was found to be more effective for in vivo development of parthenogenetic embryos, but not significantly different in the in vivo development of canine reconstructed SCNT embryos. The initiation of DNA synthesis during the first cell cycle was effectively induced by DMAP-2h treatment in both parthenogenesis and SCNT of canine embryos.

Summary: This study reports the first genome sequencing of Microctonus parasitoid wasps deployed as biocontrol agents in New Zealand. These genome assemblies serve as valuable resources for further investigation and monitoring of these biocontrol systems. Understanding the biology underlying Microctonus biocontrol is crucial and the discovery of a novel virus may contribute to the premature mortality of the host pest.

Summary: A study using paleolimnological methods revealed the long-term genetic dynamics of an obligate parthenogenetic panarctic Daphnia pulex population during colonisation and establishment in Lake Fukami-ike, Japan. The research showed that limited genetic diversity did not impede the population from establishing and thriving in a new habitat. Successful colonisation of the lake was achieved by different haplotypes, with two lineages coexisting towards the end of the study period.

Summary: This study successfully used RAD-sequencing to identify SNPs that could contribute to ash tree tolerance of Agrilus planipennis. It identified candidate genes for host tolerance and has potential for selecting cultivars able to withstand emerald ash borer infestation. Further research is needed to determine the functionality and relationship of these SNPs to tolerance of Agrilus planipennis attack.
